Problem with my router

[Jvamvakaris]

Do i understand correctly that when the House A lan port locks up and you are using static IP on laptop in house B you can not get to the internet but you can see only the two extender devices ?

When it locks up -
Does the House A router Lan port still have two lights on (corresponding the correct speed 1000 Mbit or 100 Mb - check manual) ?
Or do either of the lights go out (Left Hand side or Right Hand Side or both ) ?

Or does the RHS light stop blinking (either single color or two colors) or stay constant ON ?


If so, then-
Try replacing the network cables one at a time with a known good cable - 1) between House A router lan port and its POE injector, 2) POE injector and wireless extender, 3) swap POE injector devices and see if issue follows location of injector.

Since you have swapped out several routers, unless there is a common configuration mistake, i think you are left with a downstream hardware issue to isolate.

As you can see from the diagram I can access all the devices in my network exept the router in house A and I can't connect to the Internet.

I did check all the ip's. I don't see any problem. The router works for 2 days and is again down. I change the ip of the TV from .99 to .120 witch was the only problem that I could see. Now I don't have any other static ip under .100.

Now I will try to change the POE from house A to house B.

I really can't understand the reason for all that. Hopeful I will find it.

Again thank you all for the help

Have you changed out the cables with known "good" cables bteween the router and the poe injector and between the poe injector and the extender in house A ?

I have change the cable between the router and the POE with brand new. I haven't change the cable between the POE and the antenna. Is 10 meters long goes 2 floor up. The network stays up 3 days and then goes down again. I disconnect the POE from the router and connect it again after a minute then everything works.

Given the length of the cable from your POE injector and the extender the voltage drop might be the source of your problem. Three possible solutions, if current cable is copper clad aluminum replace with solid copper cable, replace POE injector with gigabyte injector which will use two instead of one pair or use slightly higher voltage at near end so that at far end voltage is at needed level.

Ela Gianni,
One thing you can try is disable the DHCP from the router A and enable the DHCP on router B to work instead.
just remember you cannot have 2 routers both using DHCP
Fix your IP pool 192.168.1.100 to 192.168.1.254 so static address are reserved for 192.168.1.1-192.168.1.99
also if you only use 3 computers why not give them all a static IP and see what happens. this way you avoid DHCP altogether.
I have also noticed with lower end routers, they can't handle a lot of traffic, many routers after a few days of abuse end up crapping out.
if the problems still continues I would suggest you change router A to a higher quality like ASUS they are very robust and will handle a lot of data without them crapping out. 68U for example is a fine router.
But I think having router B do the DHCP may fix your problem.
Also if the cable you have goes outside it is recommended to use an exterior cable that has lubrication inside.
I had a cable from my house to my studio it was 50 meters long. When it gets cold or humid the cable expands and contracts and usually causes shorts and weird things happen. When i changed the cable to exterior it worked fine for a couple of years before I had to change it again. Also the cable should be very good quality. When using cheaper quality cables they end up drying up real quick and shorting out.

when you disconnected the poe injector and then connected again, you rebooted the extender and forced it to establish both links again.

When the router lan port was not functioning, what was the status of the port lights before you did the above ?

What is the wattage the poe injector is rated for ? 15 or 30 watts ? What does the extender require min/max ?

You can also try changing the location of the poe injector to be close to the extender to test if voltage drop is an issue by switching the location of the two cables.
10 m should not be an issue for 100 m bit unless the cable is faulty. If the power budget is too close, or the injector is weak, or the AC power to the injector is not stable, you could see intermittent dropouts.

You mentioned earlier that even with the router lan port not "functioning", you were able to communicate with both of the extenders. I assume this meant you could edit the configuration or ping the one in house A from the house B side. Is that correct ?

Did you do a test setup of all the hardware and cables before installing to verify it worked ? ie:
have you tried placing both extenders in house A with the A router and your laptop or other computer connected by wire to the B extender to see if that setup is stable ?

I was working far from house for some days and didn't have time to check the messages. Well the network from what I've seen it does the same. Work for 2 days then again is down. I don't think that is the voltage because it use to work at the beginning. I'm going to change the POE from house B to house A to see if the problem will move to house B.
Thank you for the responds i will get back for the results.

Hi again from Greece.

Af a really long time, I manage to find the problem with my connection.

I haven't mention that the wire that runs from my POE to my antenna runs through my neighbors roof. When I install it I ask them and hi also help my install it. But His WIFE use my wire as a string for hanging clothes for dry out in the sun. I had a metal string installed with the wire to support it but this didn't hold eather. Finally I reroute the wire and Chang it and now all works well.

THANK YOU ALL for the advices and for the time you spend with me. If you ever come to greece send me a message. ....

Thanks for reporting back. So why were clothes on the cable causing a problem?

I would assume the weight of the clothes made some short inside the wire over time.
The moral of the story is networking and laundry don't mix

 

[L&LD]

Heavy, wet clothes in 40C and humid weather would do that to a cable.

Ah, those Greeks!

Yea being that I am Greek as well its OPA time so let's dance on the Wire LOL

 

[Jvamvakaris]

Well the problem is that the weight of the clothes pull the wire from the connector. The wire got loosen but not disconnected. That's why I didn't see it from the start. It was still in attached to the antenna and looked well. Sense I had constant up and down in the network I didn't think that the wire would be cut. I didn't expected to work some times.
Bye the way all worked well now. OPA...

FWIW - doing an overhead span - always helpful to put a support with the wire... parachute cord works well enough for this..

The wire itself shouldn't be the only means of support.
